Matt Gleason had skipped getting a flu shot for more than a decade.
But after suffering a nasty bout of the virus last winter, he decided to get vaccinated at his Charlotte, N.C., workplace in October. "It was super easy and free," said Gleason, 39, a sales operations analyst.
That is, until Gleason fainted five minutes after getting the shot. Though he came to quickly and had a history of fainting, his colleagues called 911. And when the paramedics sat him up, he began vomiting. That symptom worried him enough to agree to go to the hospital in an ambulance.
